Edward Weston could go from a closed camera case to an exposed negative in 2 minutes and 30 seconds.

Yes, there are ways to get things fast - the right gear, enough time spent using it to where it becomes like driving your car or getting food from the plate into your mouth, and keeping everything as simple as possible - one lens, knowing the correct exposure for a sunny day with no snow on the ground, etc. etc. etc.

I would not argue that a monorail is necessarily any slower than a field camera - yes design is important, but so is working with it. I'll bet someone who knows their Technikardan well could out-do old Ed'ard today.

There are ways to expidite things, little tricks, but I know my wife can barely sit still long enough for me to work, and we don't have any kids. There are some really nice 6 X 9 rangefinders out there - old Mamiyas, KoniOmegas and the new Fujis....
